PURPOSE:To limit the maximum temperature of the titled device when the device is out of water at the time when the sun is in the south so that deterioration of a heat collector may be prevented by installing a heat storing material in a heat collecting pipe or header. CONSTITUTION:In a solar heat collector of a plate type or of a vacuum tube type comprising a glass sheet 1, heat insulating material 6, heat collecting pipe 2 and header 8 (condensation section), heating maxium temperature void of water at the time when the sun is in the south by installing a heat storing member 11 in the heat collecting pipe 2 or header 8. For such heat storing member 11, organic material such as high density polyethylene is used for the flat plate type, and inorganic material such as molten salt of NaCl for the vacuum tube type. As the heating temperature of the heat collector void of water can be controlled by installing the heat storing material, the deterioration of the heat collector can be prevented. |
